Serial No. 620,781.

To all whom it may concern:

Be it known that we, JOHN S'runaocit, a subject ot the King oll (li-eat Britain, and DUNY A. Somrr'r, a citizen oit the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Lid-Retaining Mechanism, of which the tollowing is a specification.

Our invention relates to means for Ayieldingly retaining a lid, which is hinged to one side of a receptacle, either in a closed or open position, and is adapted in particular for use in connection with the feed hopper-s of grain drills, and consists o't a spring having one end secured to the end wall of the hopper, and its opposite end adapted to contact with heel portions upon opposite sides of a movable member of the hinge connection in a manner to yieldingly retain the lid in an open or closed position; the. object ot our invention being to provide simple, cheap and etlicient means for the purpose required. Ve attain this object by means of the mechanism illustrated by the accompanying drawings, in which- Figure l represents a top View oit one end of a feed hopper for grain drills with the hinged lid in an open position and having our invention connected therewith; Fig. Q is an end elevation of Fig. l representing the lid of the hopper in its open position; and Fig. 3 is a similar figure representing the lid in a closed position.

The same reference cha acters designate like parts throughout the several views.

1 represents the side walls ot the hopper that are inclined inward and downward, Z the bottom, 3 one of the end walls thereof, and t the lid. The end walls ot such hoppers are commonly made of metal, and 5 represents a laterally projecting cylindrical hinge member integral with an end wall of the kind indicated and located at one ot its upper corners. G represents one of the hinge members that are secured to opposite ends of lid l and provided with an ear member 7 having a lateral opening therein that loosely receives the hinge member 5 in a manner to turn about its axis. The ear member 7 .is provided with heel portions 8 that are arranged at substantially right angles with each other and diverge toward the part G upon opposite sides ot the axis ot the hinge. The heel portions are preferably provided with grooves upon their edges adapted to receive one end 9 of a spring 1 0 that has its opposite end provided with an eye portion '1 1 that is received by a curved socket mem ber l2 integral with the end wall of the hopper, and 13 represents a cylindrical boss projecting late 'ally from the end of the hopper and forming a tulcrum that engages with the body portion oi the spring in a manner to prevent a turning movement ot' the eye in the socket in one direction, the opposite end of the spring being turned downward at an angle with. the body portion and yieldingly held in contact with the heel portions oi the hinge member as the lid is turned about its hinge connections, the spring contacting with either surface of the heel depending upon whether the lid is open or closed.

lVhat we claim as our invention, and desire to secure by Letters `Patent, is:

l. A lid retainingmechanismincluding, in combination, a receptacle including side and end Valls, a lid having a hinge connection with said end walls, 'said hinge connection including a member having angularly disposed heel portions upon opposite sides oi the axis oil? the hinge connection, a spring having one end adapted to engage with said heel portions, the opposite end o'lf said spring being provided with an eye portion, and a curved socket member integral with one of the end walls oil said receptacle and adapted to receive said eye portion.

2. A lid retaining mechanism including, in combination, a recelitacle including side and end walls, a lid having a hinge connec tion with said end walls, said hinge connection including a member having angularly disposed heel portions upon opposite sides member engaging with the body portion of of the axis of the hinge connection, a spring said spring. having one end adapted to engage With said heel portions, the opposite end of said spring being provided With an eye portion,
